Answer:
The correct answer is option b. "The lipid bilayer is a solid at body temperature, thus protecting the cell".
Explanation:
The fluid mosaic model describes the fluid character of the cell's membrane structure as a dynamic arrangement of components that include phospholipids, proteins and carbohydrates. One of the principles of the fluid mosaic model is that the lipid bilayer that comprises the cell's membrane is solid at body temperature, thus it functions as a protective mechanism for the cell. The higher the temperature, the more fluid the cell membrane is.
Answer: The atoms in a gas move at high speed.
The atoms in a gas spread in all directions.
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
